Data and Methods Open Geospatial Data Service Data Variety Topographic Data Product Type Format Scale Product Type Format Resolution Product Type Format Extent Elevation Data Boundaries Data Download Limits Coyright & Restrictions Liability on Accuracy Policies Figure 2 Comparison framework of open geospatial data services between best practice countries This study examines open geospatial data practices in the U.S., Canada, and Switzerland, focusing on data variety and open data policies. Information is collected from the o cial websites: USGS (U.S.), NRCan (Canada), and Swisstopo (Switzerland). Platforms analysed include TopoView and The National Map by the USGS, GeoGratis by the NRCan, and Swisstopo’s main site. QGIS Desktop Version 3.28.3 is used for viewing the downloaded datasets. The study uses the comparison framework in Figure 2 to evaluate common practices in data variety and policies. The variety of topographic, elevation, and boundary data is evaluated considering the product, type, format, and scale/resolution/extent of the open data. In term of policies, the study investigates the download limits, copyright and restrictions, and liability on accuracy of the open geospatial data. Insights from this analysis aim to improve Malaysia’s open geospatial data services. TEKNIKAL 22 Buletin Geospatial Sektor Awam
